Lieutenant Spock. He's our science officer.

( though from kirk she's more than aware that spock was first officer on his enterprise )

Captain Kirk made me aware that events in your timeline were very different, he didn't tell me the nature of what caused the timeline to emerge but I understand enough.

( she understands that she might not even be in starfleet. she's not on the enterprise so that's currently her assumption even if she could just be elsewhere )
